Many thanks greydog.
I will definitely look into this.
With it being plugin and play, I take it I won't need to anything with cars ecu or computer systems telling it I have change the I drive system.
Mine was also ment to have a bmw phone with it. But that is missing, are these easy to get hold of, as not essential but if it's ment to have it, I would like to have in my 530d.
